Ready for back to school? Start the new year off right by proudly displaying what your class is learning by using these 22 Math Common Core State Standards Puzzle Pieces. Each puzzle piece has the standard and once introduced to the class, can be displayed in the classroom. As you introduce each standard, you will build your puzzle piece by piece until you have covered all the standards in Math. Your final display will be a puzzle created by your class showing everyone just what you have accomplished throughout the year! Reusable year after year!
